I want to personally let Hank know, if these videos came out while I was in highschool, I think i would have become a molecular biologist... While i may have not gone down this career path, i know WITHOUT A DOUBT you inspire many kids to reach a level of academic competence they would have not attempted with out you. Hank, thank you for the amount of work you do. I notice you do virtually all of the writing for the show, and you explain things is such a relaxed normal no stress manor.. Thanks again!

[@pebblepod30]

Bacon Spaceman That's awesome Bacon Spaceman. I hope you don't let anybody get in your way either. I am 34 years old, but when I was young, I let my crazy dad get in my way of my attraction to chemistry. I wanted his approval, but instead I should distanced myself & found better role models. I am 34, now I'm starting to rekindle my old lost interests. Good Luck Brother =^) =^)

How to distinguish between cations and anions: -Cations start with CAT, cats = positivity and happiness. A functional household cannot be without a cat. -Anions start with An. You know what else starts with An? ANXIETY! ANOREXIA! An sentence like this makes me uncomfortable. So much negativity.

Thank you so much for this - I have a chemistry test coming up and I am preparing to fit these all in to my normal study routine. You explain things better than my textbook.

[@JimGriffOne]

The prefix "Per" actually comes from the word "hyper", which is the opposite of "hypo". They remove the "hy" from "per" because many people confuse hyper with hypo. When using "per" and "hypo", it is more difficult to confuse one with the other.

I Really Appreciate This Series Of Crash Course Chemistry As It Has Been An Amazing Support For Me During My A'levels, Even-Though They Are A Bit Fast, If You Are Listening To It Carefully You Can Really Understand It In A Very Simple Way. THANKS HANK GREEN FOR THESE AMAZINGLY CREATIVE VIDEOS.

[@ellieprince6561]

The IUPAC names for acids are even crazier. Chlorous acid (HClO2) is hydridodioxidochlorine. Sulphuric acid (H2SO4) is dihydroxidodioxidosulphur. Basically hydrogens bonded to the central atom are hydrido, OH's are hydroxido and oxygens are oxido. As weird as this way of naming is it actually represents structure and the properties really well.

[@elliotselby8368]

"nice"

[@LaurenMorley]

As someone who studies the more language based side of things, this was always my favourite part of chemistry.

[@emilyleader251]

I watch these multiple times before a test and they help a lot with tips for memorization and explanations. Your videos have helped me on soooooo many tests for years now

[@consavvy5754]

Just a tip for remembering polyatomic ions- Nick the Camel ate Clam Supper in Phoenix For every capitalized word, the first letter(s) is the non-oxygen atom The number of vowels in the capitalized words are the number of oxygen atoms in that ion the number of constantans is the charge ATE is the ending to all of the ions on the list Hope this helps!

[@wlomas378]

I usually refrain from saying "I learned more here than I did in class" because, realistically, these are afterall crash course series posted for ten minutes once a week instead of every day for 90 minutes. But in this case, this video did help me understand the use of some of the prefixes and suffixes for acids better than my AP Chem class did, so thank you for that :D

[@emilie4715]

hank i know you guys aren't really in to math but could one of you PLEASE do a crash corse physics lesson? your chem playlist covers exactly what im learning right now and i understand this so much more than the way im taught at school. physics would help!

[@dienzer9098]

LOVED THAT INTRO!

[@coda3223]

Crash Course Team: Have you thought about compiling a list of FAQs that follow the release of each episode so that in the event that a teacher wants to use your videos as a lecture replacement they could plan activities to address the FAQs? Perhaps a forum would be a better net to catch questions in, and perhaps have volunteers help answer questions. (I would definitely volunteer my time to answering ppl's Qs and helping to develop a FAQ for each episode. Btw, I'm a chemistry teacher.)

[@creatureoftheabyss1]

According to Wikipedia (I got curious and looked it up), Cation/Cathode and Anion/Anode have the same Greek root words. An anion (−), from the Greek word ἄνω (ánō), meaning "up", is an ion with more electrons than protons, giving it a net negative charge. A cation (+), from the Greek word κατά (katá), meaning "down", is an ion with fewer electrons than protons, giving it a positive charge. And that's why your Anode has a negative charge and your Cathode has a positive charge.

[@Thought-Cafe]

We're still the same, we just have a new name! :)

[@lindaa7373]

Yes, of course we learn it in school! But if you haven't learned something in a long time, sometimes you forget, so this is helpful for people who learned these things a long time ago.

Thanking God you exist. I can finally understand chemistry

[@turtle4llama]

I took Chemistry somewhere around the switch, so I learned both with my chemistry teacher growling about making it unnecessarily difficult for people who wanted to read older chemistry texts. To me, ferrous and ferric makes more sense.

[@sunriselg]

I am confused. my mother tongue is German, the German dialect of Chemistrian is a bit different than the English one. And as do understand a bit of French and Dutch, I prefer the rainy meadow in Belgium.

[@jacobgolden9482]

Not usually. Most transition metals can for various cations but no anions. For instance Iron, as shown in the video, usually is found as either the 2+ or 3+ ion.

[@thehearth8773]

Under normal circumstances. You can coax metals into negative oxidation states sometimes, especially the alkali metals.

[@Grimeaper]

I have learned something about myself and that is I am weird. Even though this video exist and it hurts my brain, and even though I do not like math. I love the idea of going to college and majoring in mechanical engineer, and minoring in chemistry. I must like torture, both of these seem hard as balls, but there is something magical about them that draws me to them. My brain may explode by the end of college when I go back but it will be worth a try.

[@Grimeaper]

Roy Fresh It isn't that I hate math (I always word things wrong) for some reason I have a mental block on it. I love the idea of learning the math I do I mean it gives you the ability to predict a lot of stuff. It will be extra hard for me, but I figured out how to work around it. I need to see the math worked out in real life like what can you use it for, I don't know how come but when I watched a video of how you would use some formula I forgot now sadly but it clicked my brain said yeah I got this, but if you throw a book at me and expect me to learn it on my own my brain doesn't want to do it that way. When I was in college the first time they threw a book at us basically and said you have to do it out of the book and do it online. They basically threw you into the deep end of the pool and expected you to swim, and the only way I could learn it was via youtube videos, the book never works for me. I honestly think I have it, it will be difficult but I think I do, once I go back to college and get beyond speech class I will make math my bitch. What do you think of masters in mechanical engineer and minoring in chemistry?

[@Grimeaper]

Roy Fresh I know it will be balls hard but I drool at the prospect of learning it (literally). The only obstacle I really truly face is the speech class. I have been out of college myself I will be about 28 or so when I go back if life events doesn't stop me from going back. What I really hate is that I live in the capital of my state in a big city and the colleges around here do not have what I need, and these are some major colleges. I have to travel over an hour to get to a college that will do. I am glad I completed some college work before having to quit. Hell when I was originally going to college I wasn't sure what I wanted to do I just went for the fun of it to see if I was smart at all. I quit with a 3.7 gpa so I guess I was kinda smart. Right now events in my life are not so great to say the least so going to college may not happen which pisses me off because I really really want to go. I think I might even be ready for speech class, I mean I used to not comment much and now I feel like bruce lee with the comment wars that surround me and well if I can improve to the point of being able to comment on stuff and have people attack me all at once and be able to win per se I think I can do speech. I got into an argument with someone and I dragged him through the mud, and he had a masters in science education talked with a friend and he was an 11th grade biology teacher I am not going to lie that gave my ego a boost. 8th grade drop out over here, G.E.D diploma and at most a year of college and I did that, I always wanted to hand a teachers ass to him on a silver platter but never thought I would have the chance, much less one so high on the food chain, but I found out through my ex wife that being a teacher does not mean you are smart she was as dumb as a bag of bricks, and he made my jaw drop in awe of his stupidity. Sorry the latter was unnecessary but I think that also helped me realize my potential, then there is a debate with bill nye and richard dawkins and so and so forth I call it the gather of the great minds that helped me, and then there is a lot of people calling me smart (including an outside source a professor of mine) all the time so I decided why not. My goal which is laughable is to somehow go to the moon or mars and maybe bring back a few moon rocks (or martian rocks of course after nasa examines them), my mom said I better bring her some back if I go to the moon lol. I have my life planned out for after college I have issues with planning stuff out. I was wanting to work with nasa for a while pay stuff off and go to the moon, and eventually go into what I call leisure work life where I become a freelance mechanical engineer that way I work around my schedule, even have a website concept down. Oy vey I really need to stop with these rants, I never used to like writing much less now but I never seem to make anything short when it comes to writing.

[@Georgiaboy_]

I am like that too man.

[@breakofrite]

Grim reaper I have trouble with math too but I also want to learn Engineering.

[@Grimeaper]

Roy Marth I just dove into a robotics class online that is free man did I jump into the pool with the sharks and alligators. I am doing physics which they expect me to know calculus for which lead me to learn a lot of calculus in 3 days which still may not suffice I haven't even finished algebra courses. I did decent though I made a 60 on my first test and besides this is not a certificate class so I earn nothing but knowledge which is good enough for me albeit there is no place around where I live to continue robotics so this is all I will ever learn from a school about robotics. I have to say my brain hurts from it but I am slowly getting it. I had to learn trig which was not hard well the part I learned the soh cah toa and it was fun. Also mechanical engineering turns out not to be what I wanted sorry never went through with it, but am going to do technical school soon and do a bunch of different course to get the skills I wanted. Mechanical engineering after a lot of studying up on it you do nothing that I want to do with it in fact you do not even use the math that you learn half the time it disappointed me but at least I found out. You are most of the time a glorified paper pusher who is also a scapegoat well in a lot of cases and you barely use pre algebra even though you learn some really really difficult stuff.

[@magister343]

Perfect is from Perfectum, where the "per" means "very" and the "fectum" is an altered form of "factum" meaning "done." In words like "pervade" the "per" does not mean "very" but is a homonym meaning "through." "Vade" means "go!" (That form happens to be the singular imperative, probably not the form from which the English word derives but I'm to lazy to conjugate it right now.).

I feel kinda old-school. When I took chemistry, we didn't use Iron(II) or Iron(III); we used the words Ferrous and Ferric, respectively (derived from "Ferrum", the old name for Iron). So "Iron(II) cholride" was called "ferrous chloride", and "Iron(III) oxide" was called "ferric oxide". I hope I'm not the only one watching this video who still remembers these terms. :P

[@thehearth8773]

Your use of sulfuric and phosphoric acids might confuse some people, since they're pretty much the only exceptions to the rule of "replace -ate with -ic" in that you add a -ur- or -or- in the middle. I also think you should have mentioned the older forms of naming transition metal ions (though they might be confusing as well...); there are still many cases where you'll see "ferrous chloride" or similar. Random: this nomenclature allows for some interesting names, like periodic acid (HIO4)

Who's ready for tomorrow's AP Chem exam?

There's something I'd have liked to see in this episode: With the examples, we're shown that HCl is called Hydrochloride Acid and why (=has no oxygen). What isn't really shown, however, is that HCl is largely what we refer to as "salt", as in the salt we're using most often on the food tables. With that, it could be shown what Chemistrians refer to when talking about "salts" (or foreshadowed), and that all shown examples are salts of HClO3. The -ic thus would show what the "base" acid is.

I can't be the only one here who has their chemistry final exam tomorrow ._.

[@thesk8erdav]

twins!

[@babakhanoushii]

***** :O (btw I failed that final)

[@thesk8erdav]

Yeah it's tomorrow. I'm playing Xbox and "yoloing" it

[@lizveramatos9205]

I love crash course. My teacher plays these and they help us A LOT!

You guys seriously need to start teaching the teachers!!! I can sit through hours of lectures and classes and pick up on very little but just a couple of ten minute videos has taught me everything I need to ace an exam, it's astounding!! They should just stop their silly and overly complicated way of teaching and just play your videos (with a few pauses between concepts for note taking haha), they're so straightforward and cut out all the noise that teachers use to try to 'engage' us. The amount of people I see using your videos to learn these concepts is amazing, and I go to the University of the Sunshine Coast in Australia! So grateful for all of these videos. Excited to watch the philosophy ones even though Im not studying that haha When I get on top of my debt I will definitely be donating!

Now i wanna visit Belgium... :| wait, im in germany, i just can do it XD

[@Oberonjames]

Belgium is awesome. I've always wanted to visit. They have the best beer, the best comics, the best chocolates and the diversity of the spoken languages is fascinating.

One problem is the large number of isomers that organic molecules can adopt. Try for example; Tetracarbon decahydride (C4H10) This could be either CH3-CH2-CH2-CH3 (butane) or it could be CH3-CH(-CH3)-CH3 (2-propane). This is the simplest case. Once you start dealing with larger molecules with 10, 20 or more carbons the number of isomers continues to increase. Throw in different functional groups (alcohols, ketones, etc.) and it becomes a nightmare. A more complex naming system was needed.
